Abstract (en)
[origin: EP3258159A1] A minimal lubrication device comprising a tank (2) for storing a lubricating fluid, means (6) for raising the pressure of said lubricant and means (81) for supplying the pressurized lubricant to at least one modular element (50A, 50B...), at least one modular element comprising a lubricating fluid conduit (90) intercepted by a flow regulator (84) and a compressed air conduit (810), such conduits being fluidically connected to an air and lubricant mixing element (88), the flow regulator (84) comprising a shutter (713) that can be at least partially housed in a calibrated hole (710) and movable between an upper end of stroke position and a lower end of stroke position, the calibrated hole (710) being in fluid communication, on one side, with a delivery of said means (6) for raising the pressure of the lubricant and, on the other side, with said mixing element (88), the shutter (713) having at least one conical profile portion (713A) insertable in said calibrated hole, characterized in that the conical profile portion (713A) has a surface groove (714) facing a surface defining said calibrated hole (710) at least when the shutter is in an intermediate position between said lower end of stroke position and said upper end of stroke position.
